Abstract
A crude benzene product pipeline with crude benzene cooling water serving as a heat-tracting medium belongs to the technical field of crude benzene delivery and solves the problems that a method of an existing crude benzene delivery pipeline for removing blocked freezing is prone to enable crude benzene to vaporize, and combustion and explosion are prone to happen. The crude benzene product pipeline with crude benzene cooling water serving as the heat-tracting medium comprises a delivery pipeline, a heat-tracing pipeline and a thermal insulation layer, wherein the thermal insulation pipeline is covered on the delivery pipeline, the heat-tracing pipeline is spirally wound on the outer surface of the delivery pipeline along the axial direction of the delivery pipeline in the thermal insulation layer, and the heat-tracing pipeline is used for leading in back cooling water output by a crude benzene lean oil cooler. The crude benzene product pipeline is suitable for heat tracing of crude benzene product pipelines.
Description
Technical field
The utility model relates to a kind of crude benzol product conduit of crude benzol cooling water companion heat, belongs to crude benzol conveying technology field.
Background technique
In process of coking, the crude benzol product finally will output to oil depot district crude benzol storage tank through conveyance conduit from the crude benzol middle groove, and in winter, at extremely frigid zones, the conveyance conduit of crude benzol product takes place to block up through regular meeting and freezes phenomenon, and this can influence normal production.At present, solve the stifled method of freezing of conveyance conduit and typically use saturated vapour companion's heat or the said conveyance conduit of chuck more than 100 ℃, and the crude benzol product is more than 90 ℃ the time; A large amount of vaporization phenomenons can appear; And be prone to produce burning and blast, therefore, can produce great potential safety hazard.
Summary of the invention
The utility model is to solve stifled method of freezing and be prone to make clumsy appearance vaporization and be prone to produce the problem of burning and blast in order to solve existing crude benzol conveyance conduit, and a kind of crude benzol product conduit of crude benzol cooling water companion heat is provided.
The crude benzol product conduit of the said crude benzol cooling water companion of the utility model heat, it comprises conveyance conduit, it also comprises TRACER road and thermal insulation layer,
Conveyance conduit outer cover thermal insulation layer, the TRACER road axial screw along conveyance conduit in thermal insulation layer is wrapped on the outer surface of conveyance conduit,
The TRACER road is used to feed the cooling water backwater of the oil-poor cooler output of crude benzol.
Said thermal insulation layer is the heat-preservation cotton layer.
The utility model has the advantages that: the utility model adopts the companion thermal medium of the cooling water of the oil-poor cooler output of crude benzol as the TRACER road; Because the temperature range of the cooling water of the oil-poor cooler output of crude benzol is constant; Therefore can guarantee effective companion's heat, thereby reach, simultaneously in the temperature companion heat rating of the utility model scheme the anti-blocking antifreeze purpose of conveyance conduit to conveyance conduit; Can not cause the vaporization of crude benzol product; Can not cause the burning and the blast of crude benzol product yet, both guarantee the safety of producing, reach the effect of energy-saving and emission-reduction again.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
Embodiment one: below in conjunction with Fig. 1 this mode of execution is described, the crude benzol product conduit of the said crude benzol cooling water companion of this mode of execution heat, it comprises conveyance conduit 1, it is characterized in that: it also comprises TRACER road 2 and thermal insulation layer 3,
Conveyance conduit 1 outer cover thermal insulation layer 3, TRACER road 2 axial screw along conveyance conduit 1 in thermal insulation layer 3 is wrapped on the outer surface of conveyance conduit 1,
TRACER road 2 is used to feed the cooling water backwater of the oil-poor cooler output of crude benzol.
When this mode of execution is used for practical implementation, the medium inlet end on TRACER road 2 and the outlet end of the oil-poor cooler of crude benzol are linked together, can realize companion's heat, ensured normally carrying out of extremely frigid zones coking in winter production thus TRACER road 2.Thermal insulation layer 3 can effectively prevent heat scattering and disappearing to the external world.
The temperature range of the cooling water backwater of the oil-poor cooler output of crude benzol is 30 ℃ to 60 ℃.
Embodiment two: this mode of execution is for to the further specifying of mode of execution one, and said thermal insulation layer 3 is the heat-preservation cotton layer.
Heat-preservation cotton has the characteristics of firm and good heat insulating, can reach the insulation requirement to conveyance conduit 1.
Claims (2)
